CONDENSER FOR "USE WITH REFRIGERATOES.

Application filed August 7, 1923. Serial No. 656,191.

To all whom it may concern;

Be it known that I, EMIL Klior, a citizen of Switzerland, residing at VVinterthur, Switzerland, 122 Jonas Furrerstrasse, have invented certain new and useful Improvements in Condensers for Use with Refrigerators, of which the following is a speci fication.

This invention relates to condensers more especially adapted for use with refrigerators having a liquefying chamber in the form of a coiled tube, and has for its object to provide in a compact form a condenser having a large cooling surface.

The invention consists in the coiled tube being disposed in a cooling water conduit formed between the two parts of a cylindrical double wall. The coiled tube and the cooling water conduit are preferably both in, the form of a cylindrical helix. Conveniently the outer part of the double wall is divided into at least two portions, the inner part preferably being similarly divided.

A construction according to the invention is illustrated by way of example in the ac companying drawing, in which Fig. 1 is a vertical section through the condenser, and

Fig. 2 is a horizontal section taken on the line 22 of Fig. 1.

The refrigerating medium, which is to be liquefied in the condenser, passes downwards through the helical tube a. This tube a is disposed within the helical space d formed between the inner and outer parts I) and 0 respectively of a cylindrical double wall. The cooling water is caused to flow upwards through thespace (Z past the outside of the tube a. Owing to the arrangement of the tubes and to the fact that cooling water is flowing in a direction opposite to that of the refrigerating medium, a very considerable cooling action is obtained.

The outer part c of the double wall is divided into two portions connected together by flanges e, to facilitate assembling the condenser and opening up the cooling water passage d for cleaning purposes. The inner part b of the wall may be similarly subdivid ed if desired.

It will be understood that although the condenser according to the present invention has been described primarily with reference to its employment with a refrigerator, it may be employed. for other purposes if desired.

I claim: I

1. A condenser especially adapted for use with refrigerators comprising a coiled tube, and a cylindrical double wall casing enclosing said tube, the walls of said casing forming a helical conduit in which said coiled tube is disposed, so as to leave a fluid circulating passage between the interior surface of said helical conduit and the exterior sur face of said tube, and the inner and outer wallls of said casing being separable from the col 2. In a condenser especially adapted for use with a refrigerator the combination of a cylindrical double wall and a cooling water conduit formed between the two parts of the cylindrical double wall with a liquefying chamber in the form of a coiled tube cylindrically bent and disposed in the cooling water conduit, the outer part of the double wall being divided into at leasttwo portions.

3. In a condenser especially adapted for use with a refrigerator the combination of a cylindrical double wall and a cooling water conduit formed between the two parts of the cylindrical double wall with a liquefying chamber in the form of a coiled tube cylindrically bent and disposed in the cooling water conduit, the inner part of the double'wall being divided into at least two portions.

In testimony whereof I have aflixed my 90 signature. EMIL KAGI.
